Naruto and Sasuke run the Rivals Gauntlet

1. Sakura and Ino
2. Kakashi and Might Gai
3. Jiraiya and Orochimaru
4. Danzo and Hiruzen
5. Hashirama and Madara

Stips
-45 minutes rest between each fight after clearing Kakashi.
-All of these characters are alive, no Edo.
-Can only use abilities when they were alive so no wood techniques or Rinnegan for Madara.
-Everyone is bloodlusted.

They don't make it past the first round because they are too busy having sex.

You mean too busy having sex with each other.

lol, anyway, I think they could clear the gauntlet since no Rinnegan or Hashirama cells for Madara. They would just have to use their Kyuubi curse mark Biju sage mode Susano'o cloaked Nine tailed fox. They did beat Jyuubito, who basically raped all four hokage's at once. To beat Danzo and Hiruzen though, they basically get Naruto to slash him a bunch and stall him until he runs out of Izanagi, and Sasuke can skewer Hiruzen with EMS Amaterasu blade in an instant, since he can't use substitution jutsu indefinitely. Jiraya and Orochimaru would probably be the hardest though if both were in their primes. Hashirama and Madara would require the hax Susano'o wearing Kyuubi with all kinds of other shit though.
